rulloyd Posted March 21, 2021 Report Share Posted March 21, 2021 Anybody else noticed that the filter (which seems to incorporate a valve) in new new Tudor bottles is too tough for the bellows or even a small pump? Wondering if I have duff one. Fine when I take it off. Rich Link to comment Share on other sites More sharing options...
Pete Lewis Posted March 22, 2021 Report Share Posted March 22, 2021 should be able to pop it apart its a simple disc plate valve it shouldnt be restrictive so yes it sounds a bit duff Pete Link to comment Share on other sites More sharing options...
Colin Lindsay Posted March 22, 2021 Report Share Posted March 22, 2021 Buy another one from any Aquarium supplies; they use them in fish tank filters and they're very cheap to buy. Link to comment Share on other sites More sharing options...
DVD3500 Posted March 22, 2021 Report Share Posted March 22, 2021 Yep. I did that. I put one in before and after the pump/bellows and it works fine! Link to comment Share on other sites More sharing options...

rulloyd Posted March 22, 2021 Author Report Share Posted March 22, 2021 Is it a valve or a filter or both? Why does it need a valve? Struggling to find something. If anybody can point me at a suitable aquarium jobby that would be great!! Thank you Rich Link to comment Share on other sites More sharing options...

Pete Lewis Posted March 22, 2021 Report Share Posted March 22, 2021 it not a waste of time small problems like screen wash are very valid when its a MOT failure or the need for common sense to prevail when legally to be on the road they must be working Pete Link to comment Share on other sites More sharing options...
DVD3500 Posted March 22, 2021 Report Share Posted March 22, 2021 It is also called a check valve or non-return valve. It is not a filter. Essentially it only lets liquid or air move in one direction. Just like a plastic bottle of ketchup: if you squeeze the begeezus out of it drown your hot dog in mildly seasoned tomato guts the bottle will not return to its former shape. You have to let air in to replace the ketchup you ejacul... ejected... The pump/bellows works similarly but without the valve the water gets sucked back into the bellows. The water just goes back and forth because as the billows expands it sucks the water back in. For S&Gs you can operate it without a valve and as soon as you put your finger over one end it will squirt but it will try to such air back in through the nozzles. While I was at it I also bought a length of silicone piping in case my set up needs modifying or breaks. 2 valves, 5 meter of hose/piping (there were no shorter lengths available when I ordered) and a T piece cost my 12 € delivered... 1 Link to comment Share on other sites More sharing options...
Colin Lindsay Posted March 22, 2021 Report Share Posted March 22, 2021 The aquarium versions are only 99p, you can put them on the end of the line, or inline. 1 Link to comment Share on other sites More sharing options...
DVD3500 Posted March 22, 2021 Report Share Posted March 22, 2021 Yep.. those are the ones I used. If you're not sure which way round to put them in just blow in one end. Air can only go through one way... Link to comment Share on other sites More sharing options...
